Once the most abundant and important reef-building corals in Florida and the Caribbean, elkhorn corals have declined by more than 90 percent in many areas, mainly as a result of disease and “bleaching. The diffuse ivory bush coral thrives in areas of high sedimentation including hardbottoms, lagoons, and back reef areas to depths of 40 feet (12.2 m). The disease affects certain coral species more than others and often kills the whole coral colony. Losing coral reefs could result in cascading effects to the Florida Keys region’s economy and culture, which are firmly rooted in the local marine ecosystem. Reefs make up 1% of … The disease affects certain coral species more than others and often kills the whole coral colony. "Pillar coral is an extremely challenging species to collect eggs and sperm from in the wild and raise large numbers of offspring," said Keri O'Neil, senior coral scientist at The Florida Aquarium. This leads to significant declines of susceptible species on impacted reefs. As the coral polyps gain extra nutrients from the zooxanthelle, the … © Pierre Fidenci A healthy coral reef supporting a high density of fish larvae. Large-scale coral bleaching has progressively become more widespread and severe. Covering less than 0.1% of the seabed, coral reefs are home to 25% of the world's marine species. This brain coral appears green to brown or yellow brown in color with valleys often of a lighter color. The coral looks like a human brain. The importance of nurturing these healthy corals was underscored in April when O’Neil led a multi-agency expedition to “release” 3,000 Aquarium-raised staghorn corals in selected sites off The Florida Keys. In other species, coral growth in high nutrient environments has been reported to increase although areas of new growth exhibit reduced … 16 - Endangered Species Act. There are more than 800 species of coral throughout the world’s oceans. The short branches are crooked with raised corallites. Due to pervasive threats like climate change, the National Marine Fisheries Service has listed seven Caribbean species of coral as threatened under the Endangered Species Act. When the destruction of the coral reefs began to take place, the over fished fish were going from threatened to endangered. This coral is found in most reef habitats, from mangrove areas and back reefs all the way out to the outer reef and wall. The dredging is part of an effort by the Corps to expand ports along the East Coast to accommodate larger ships. Forming round boulders, colonies have deep interconnected valleys that contain polyps along with broad ridges that have wide, trough-like grooves running down the middle. Boulder Star Coral – Monstastrea annularis. The largest of all these reefs are found in shallow, tropical, and subtropical waters, and one of the very biggest of those — and the most endangered — is the Unfortunately, Florida’s reefs are in dire trouble. In response, scientists launched an unprecedented rescue effort to save the corals. It is commonly found at the back reef, although much larger specimens may be found on the fore reef zone. Locally, impacts to the reefs come from misplaced boat anchors, ship groundings, pollution, overfishing, storms, and disease. Some species of hard and soft corals, known as hermatypic corals, host a type of algae known as zooxanthelle within in their gastrodermal cells. Aquarium researchers are working on different approaches to save multiple endangered species of coral that are imperative to the restoration and overall health of the Florida Reef Tract. In deeper waters, this coral has been observed growing as a plate formation. That's why these 20 species—which include pillow corals, three species of star corals, and rough cactus coral—have been classified as "threatened," rather than "endangered." Colonies cover acres of shallow reef bottom, just below the low tide line. Coral reef systems provide crucial shelter, food and breeding sites for countless marine plants and animals, including species that are commercially and recreationally valuable. Coral Reefs: Introduction, classification and anatomy Coral feeding, nutrition, gender and reproduction Coral reef growth, forms and structure Global Distribution and status of coral reefs The coral reef ecosystem, its ecological functions and economic value Threats (Part I) Threats (Part II) Protecting coral reefs Bibliography and additional readings Florida’s Coral Reef needs active management to maintain existing reefs, restore those that have been injured, and prevent additional impacts.

The species we are working with are critically endangered, particularly the staghorn and elkhorn corals which have seen their populations decline by up to 97-percent along the Florida Reef Tract in the last 40 years. Unfortunately, this … Scientific studies into effects of nutrients on coral reefs have shown that high levels of dissolved inorganic nutrients, such as nitrogen and phosphorus, can reduce coral growth and calcification rates in some coral species by up to 50%. Species seen by many snorkelers in national parks, elkhorn and staghorn corals, are both considered to be critically endangered. They also protect coastal residents because they buffer storm damage. Solitary species include the mushroom coral Fungia scutaria species. An estimated 4,000 fish species, and some 25 percent of marine life, depend on coral reefs at some point in their existence. Massive Starlet Coral – Siderastrea siderea. Elkhorn coral. All forms are tan to yellow-brown, gray-brown, or brown with purplish tinges. The lower portions are usually bio-eroded and colonized by algae. Found 10-160 feet (3-49 m) below the surface in protected clear water, colonies cover large areas of the reef. Seven coral species are listed as threatened under the Endangered Species Act. The damage stemmed from the Corps’ failure to collect and use accurate, up-to-date information or adequately account for potential impacts to nearby reefs. © Pierre Fidenci Porites species with sea weed encrusted in its center.
